.To a/Zlwhom it may concern: l

Be it known that I, .HENRY CHANNON-1 a citizen of the United States, .residing at Chicago, countyof Cook, State lof-Illinois, have 5 invented a certain new and useful im revement in EXcavatingBuekets and f eclare the followingtobe a full, clear, and exact' def *ription of the invention, suchas will enable others skilled in the art to which it pertains 1o to makegand use the same, reference being had to the acompar ing drawings, which form a part of this specification; l.

My invention relates in general to exeavating apparatus, an more particularlytoan,

t5 ein:avatiiig-shovel. v i I. In the Work of eXcavatin' it-isnecess'ary that. .the shovel vor buckets iould be forced into the material ,until iilled, then. heldinto Eosition to retain the materialtherein while 2O permitted to'dump the material therefrom. Q

"The primaryobjectof my invention is to.

which may bereadily` loaded with material,

may be easily dumped. when above the-posi-Y tion wheretheniaterial is to be deposited.A

-A further object of iny invention is to pro- 30 vide anexcavating-shovel which will be sim# ple in construction, inexpensive in .manufactur, and efficient in use.

The embodiment of my invention herein disclosed may be generally described ascom'- 35 prisnga shovel, a supporting-bail between the arms of which the shovel is pivotally suported at the rear of itscenter of gravity, a ell-crank lever on each side of the shovel, one arrn of thel lever being pivoted to the? 4o shovel, a link connecting,r the bell-crank le veradjacent its angle with the bail above its fulcruni, and hauling mechanism. con- .neet-ed with the other arm of the bell-crank' lever on each side of the shovel. A y 45 M invention will be more'fully described hereinafter with'reference to the accompany@ ingdrawings, in which the. sarneis illustrated as embodied in a convenient and practical form, and in which# I 5o Figure-1 is a side elevational view Showing the-bucket in position toy dig into the mate-' rial Fi 2, a View similar to F 1, showing' the one et when filled with material; Fig. 3,

A link D connects each bell-crank lever with the portion of the bail B on the correio of the link D is pivotally secure( or other power device.

A.bucket to Aassume a substantially4 horizontal sponding side of the bucket. One end of the link D is pivotally connected by a screwthreaded bolt d? to the bf il at a point a short distance from its fulcrum. The o osite end y screw-Y threaded bolt d to the 'bell-crank lever at a point adjacent its angle.

The manner of using and operation of my improved excavating-bucket are as follows: The bucket is located at the point where the material is to beremoved by means of the lifting-cable F, which depends from a derrick, crane, or other supporting mechanism. The shovel or bucket is then moved horizontally by power applied to the hauling-cable E, which is operatively connected toa windlass The horizontal movement of the bucket causes it to di into the earth or other material, -thereby `llin the bucket. Afterthe bucket has been fille the tension of the hauling-cable E` causes the position, such as shown in Fig.2, owing to the links D, which connect the bell-crank levers with the bail. The bucket While held in a substantially horizontal position may be moved to the desired position where the material is to be deposited when the tension on the hauling-cable E is discontinued, thereby permitting the bucket to swing relatively to the bail to the osition shown in Fig. 4, when the material-wi l at once fall from the bucket. It is obvious that when the bucket is in the substantially horizontal position shown in *.io Fig.- 2 it cannot oscillate between the arms of the bail without the ends of the links D2, which are pivotallyr connected to the bails, moving toward the rear of the bucket. Such rearward movement of the links is prevented' as long as the bell-crank levers are retained in the position shown in Fig. 2. When, however, the tension on the hauling-cable is discontinued, the bell-crank leve are permit-v ted to oscillate rearwardly, and rence permit 5o the links tov move toward the` back of the bucket, thereby permitting the bucket to swing downwardly and dump the material.

The cable'E, bail C, toget er with the bellcrank levers, and links D constitute the pulli mechanism by means 'of which the bucket is auled horizontally and loaded with material. From the foregoing description it will be observed that I have invented an improved 6o excavating-bucket which though sim le in construction ma be readily loaded wit material and when oaded securely held in position to retain the load iintil it is desired to l dump thematerial, lv vhich may be done by haulin -cable. A

In Fig. 6 Ihave illustrated'amodified form of my invention, in which the bell-crank lever "is fulcrumed intermediate of its angle and the end of its shortI arm. vIn this` view` H indicates the bell-crank lever,'fulcrumed at h upon the bucket and connected at the end h' of its short arm with the link D. The oper-I ation of this modification of my invention is the same as above described with respect to the form of the invention shown in Figs. 1 to 5, except that, when the bucket dumps, the I bail uniting the ends of the long arms Aoi the bell-crank levers swings downwardly and not upwardly.

It is-.obvious that the bell-crankf levers may be connected to the links D at the ends l of their arms and fulcrumed at a point intermediate of their angles and their connections with the links, as shown in Fi 6. In this figure H indicatesone of the bel -crank levers which is .fulcrumed upon the side of vthe bucket at h andivotally connected 'to' the link D at theend of'oneof its-arms: 'The operation of thismodiication of 'my invention is the same as that above described, ex-

cept thatthe bail C swings'downwardl'y relative to the bucket instea of upwardly.
